Challenge: Which Steeple Is the Oldest?

Googler Daniel Russell knows how to find the answers to questions you can't get to with a simple Google query. In his weekly Search Research column, Russell issues a search challenge, then follows up later in the week with his solution—using whatever search technology and methodology fits the bill. This week's challenge: Which steeple is the oldest?

Today, a slightly harder puzzle for you to solve.

Below are four pictures of steeples that I've encountered over the years. I'm quite taken with steeples, finding them fascinating, and love to take photos of them as I travel around. They're tough to build, full of symbolic meaning, and seem to always have a good story associated with them.

But today I have a simple question—Which of these is the oldest steeple? Can you identify each steeple and give its construction date?

How hard can that be?

When you solve the problem, would you be sure to say how long it took you?

Daniel M. Russell studies the way people search and research—an anthropologist of search, if you will. You can read more from Russell on his SearchReSearch blog, and stay tuned for his weekly challenges (and answers) here on Lifehacker.
